Description
Die vorliegende Erfindung betrifft Verfahren und Vorrichtungen zur Steuerung des Luftstroms um eine Tragfläche, welche eine vordere Kantenvorrichtung mit einer flexiblen Strömungsoberfläche aufweist.The present invention relates to methods and apparatus for controlling the flow of air about an airfoil having a front edge device with a flexible flow surface.
Moderne Hochgeschwindigkeitsunterschallverkehrsflugzeuge weisen typischerweise Tragflächen mit einer Vielfalt von vorderen Kantenvorrichtungen und hinteren Kantenvorrichtungen auf, um die Form der Tragfläche zu ändern, wenn sich die Flugbedingungen ändern. Derartige Tragflächen können flexible Platten an der vorderen Kante der Tragfläche aufweisen, wie in den
Ein möglicher Nachteil bei einigen der zuvor genannten Vorrichtungen ist, dass es schwierig sein kann, die Vorrichtungen anzuordnen, um sie zu hohen Ablenkungswinkeln zu bewegen und dennoch für einen Horizontalflug sauber zu verstauen. Dementsprechend stellen viele der zuvor genannten Vorrichtungen einen Kompromiss zwischen einem wünschenswert hohen Ablenkungswinkel beim Landen und anderen Bedingungen bei geringer Geschwindigkeit und einer sauberen Konfiguration, wenn die Vorrichtungen verstaut sind, dar. Ein weiterer möglicher Nachteil bei einigen der zuvor genannten Vorrichtungen ist, dass es schwierig sein kann, sie in sehr dünne Tragflächen und/oder sehr dünne Abschnitte von Tragflächen einzubauen. Dementsprechend kann es schwierig sein, diese Vorrichtungen in Hochgeschwindigkeitstragflächen einzubauen, welche typischerweise ein geringes Dicke-zu-Flügeltiefe-Verhältnis aufweisen. Weiterhin kann es schwierig sein, diese Vorrichtungen in die dünnen Außenabschnitte von Niedriggeschwindigkeitstragflächen zu integrieren.A potential disadvantage with some of the aforementioned devices is that it may be difficult to dispose the devices to move them to high angles of deflection while still being neatly stowed for horizontal flight. Accordingly, many of the aforementioned devices provide a compromise between a desirably high deflection angle on landing and other low speed conditions and a clean configuration when the devices are stowed. Another potential disadvantage with some of the aforementioned devices is that it is difficult may be to incorporate them in very thin wings and / or very thin sections of wings. Accordingly, it may be difficult to incorporate these devices into high speed bearing surfaces, which typically have a low thickness to chord pitch ratio. Furthermore, it may be difficult to integrate these devices into the thin outer portions of low speed bearing surfaces.

Es ist eine Aufgabe der vorliegenden Erfindung, die verfügbaren Tragflächen zu verbessern.It is an object of the present invention to improve the available wings.
Die vorliegende Erfindung stellt eine Tragfläche bereit gemäß Anspruch 1.The present invention provides an airfoil according to claim 1.
Die vorliegende Erfindung stellt ferner ein Verfahren zum Betreiben einer Flugzeugtragfläche bereit gemäß Anspruch 10.The present invention further provides a method of operating an aircraft wing according to claim 10.
Ein Verfahren gemäß einer bevorzugten Ausführungsform der Erfindung weist ein Bewegen des zweiten Abschnitts der Tragfläche relativ zu dem ersten Abschnitt durch Betätigen einer ersten Führungsstruktur mit einer ersten mechanischen Anordnung und ein Bewegen eines dritten Abschnitts außerhalb des zweiten Abschnitts relativ zu dem ersten Abschnitt durch Betätigen einer zweiten Führungsstruktur mit einer zweiten mechanischen Anordnung, welche anders als die erste mechanische Anordnung ist, auf.A method according to a preferred embodiment of the invention comprises moving the second portion of the support surface relative to the first portion by actuating a first guide structure having a first mechanical assembly and moving a third portion outside the second portion relative to the first portion by actuating a second one Guiding structure with a second mechanical arrangement, which is different than the first mechanical arrangement on.
